Hydrotesters

Since 1911, Fives’ Taylor-Wilson product line of Hydrotesters, Leak testers and Collapse testers has been at the forefront of hydrostatic pipe testing equipment development.

While the principles behind hydrostatic testing remain consistent, each installation has its own unique requirements. As a leader in the industry, Fives strives to be innovative and evolutionary with design improvements and continues to offer the enhanced efficiency, superior technology and safety that the Taylor-Wilson Hydrotester has always delivered.

Sealing

Our engineers have designed and produced an array of sealing devices to handle a wide variety of applications based on end conditions, O.D. variations and pressure requirements. These sealing devices include:

Traditional U-cup seal with special anti-extrusion hardened ring.

End sealing for low pressure.

I.D. sealing for critical high-stressed pipes.

Collapsing seal with traveling insert, which allows a pipe range to be tested by a common seal — for testing unfinished product, or in front of a coupling.

Pressure Control

Frequently, the test pressure procedure is affected by fluctuating pressures, thereby compromising the testing process. By using specially designed intensifiers, either oil-to-water or water-to-water, combined with the latest microprocessor-controlled hydraulic servo equipment or electronic air-over-water regulation system, we can achieve greater stability in the test pressure systems. Additionally, the test hold time can be easily varied on our testers to suit the specific standard to which the pipe is being tested - all with continuous and accurate pressure control throughout the test hold period.

Fully automatic testing of a complete API range (1, 2 or 3) of pipe lengths, without resetting the machine.

An automatic measuring system built into the alignment station to prevent pipes outside of the length tolerance from entering the test bed, while simultaneously testing and discharging previous pipes.

All pipe length, grade and pressure settings are accomplished at the operator control station, without physical adjustments required.

Testing mechanisms are designed with drop-in components to rapidly change pipe size or test cups.
